|
|
* include/hal_cache.h: Added support for ARM926EJ. Changed
|
| 4 |
|
|
ARM925T to use CYGHWR_HAL_ARM_ARM9_ALT_CLEAN_CACHE and defined
|
| 5 |
|
|
CYGHWR_HAL_ARM_ARM9_ALT_CLEAN_CACHE to clean the cache manually
|
| 6 |
|
|
because CYGHWR_HAL_ARM_ARM9_CLEAN_CACHE did not work for the
|
| 7 |
|
|
OMAP1510.
|
| 8 |
|
|
|
| 9 |
|
|
* cdl/hal_arm_arm9.cdl: Added option for ARM926EJ.

|
| 12 |
|
|
|
| 13 |
|
|
* include/hal_cache.h: Changed HAL_ICACHE_LINE_SIZE and
|
| 14 |
|
|
HAL_DCACHE_LINE_SIZE to match the documentation from TI. Now the
|
| 15 |
|
|
kcache2 test passes the two tests that it runs.

|
| 18 |
|
|
|
| 19 |
|
|
* include/hal_cache.h: Added support for ARM966E. This does not
|
| 20 |
|
|
have a cache, so this involved adding support for cacheless ARM9s
|
| 21 |
|
|
in general.
|
| 22 |
|
|
|
| 23 |
|
|
* cdl/hal_arm_arm9.cdl: Added option for ARM966E.

|
| 26 |
|
|
|
| 27 |
|
|
* include/hal_cache.h: Only define HAL_VIRT_TO_PHYS_ADDRESS if it
|
| 28 |
|
|
isn't already defined. This needs renaming and a cleanup, but this
|
| 29 |
|
|
quick #ifdef hack fixes a compiler warning.
|
| 30 |
|
|
|
| 31 |
|
|
* cdl/hal_arm_arm9.cdl: Declare var_io.h.
|
| 32 |
|
|
|
| 33 |
|
|
* include/var_io.h: Added.

|
|
|
| 37 |
|
|
* src/arm9_misc.c (hal_hardware_init): Don't invalidate caches on
|
| 38 |
|
|
RAM startup.

|
| 41 |
|
|
|
| 42 |
|
|
* src/arm9_misc.c (cyg_hal_arm9_soft_reset): Also put CPU in SVC
|
| 43 |
|
|
mode (as after a reset). Still broken though.
|
| 44 |
|

|
|
|
| 51 |
|
|
* src/arm9_misc.c (cyg_hal_arm9_soft_reset): Attempt at soft
|
| 52 |
|
|
reset. Doesn't quite work though, and it's unclear why.
|
| 53 |
|

2001-10-28 Gary Thomas
|
| 55 |
|
|
|
| 56 |
|
|
* include/hal_cache.h: Fix DATA cache flush for 920,922. This was
|
| 57 |
|
|
off-by-one, leaving part of the cache unflushed.
|
| 58 |
|
|
|
| 59 |
|
|
2001-08-13 Jesper Skov
|
| 60 |
|
|

2001-04-30 Gary Thomas
|
| 64 |
|
|
|
| 65 |
|
|
* src/arm9_misc.c (hal_hardware_init): Use CDL configuration to
|
| 66 |
|
|
decide which caches should be enabled at startup time.
|
| 67 |
|
|
|
| 68 |
|
|
2001-04-26 Gary Thomas
|
| 69 |
|
|
|
| 70 |
|
|
* src/arm9_misc.c (hal_hardware_init): Caches just don't seem to work.
|
| 71 |
|
|
|
| 72 |
|
|
* include/hal_cache.h: Fix cache parameters - 16K x 16K
|
| 73 |

|
|
2001-04-18 Jesper Skov
|
| 75 |
|
|
|
| 76 |

|
| 91 |
|
|
|
| 92 |
|
|
* include/hal_cache.h: Consistently ensure that ARM registers used
|
| 93 |
|
|
in MCR ops to cache-control coprocessors, where the data doesn't
|
| 94 |
|
|
matter, all actually have data zero ("SBZ") as in the Jaggar book.
|
| 95 |
|
|
This may well not be necessary, but for the sake of making sure...

| 99 |
|
|

|
| 101 |
|
|
|
| 102 |
|
|
* src/arm9_misc.c (hal_hardware_init): Disable caches. Wasted too
|
| 103 |
|
|
much time on this already.

| 108 |
|
|
to clear.

|
|
| 130 |
|
|
